When an object (stone, spear, arrow or bullet) is thrown, hurled or shot in the air, the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not, he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food.
In today’s sports, balls follow projectile motion...

Force: This can be defined as a pushing or pulling action that causes a change of the state of a body. A long jumper who wants to increase their degree of force will need to increase their weight, but this can negatively affect their speed, so it is vital to get the balance right.

The motion of assemblies is determined by the configuration of links and joints. Using the configurations the operation of rotational and sliding joints are examined and observed. This kind of mechanism is very commonplace in machines. Machines are made up of a number of parts and relative motion between the various parts permits the working of the machine. As the crank is rotated the rod starts moving but the velocity is not uniform. It is greater...

Objective: To study the conservation of energy and momentum using projectile motion.
Theory:
The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction, the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system, if no net external force acts on a system of particles, the...

The Physics of Field Goal Kicking
Physics is involved in all of our daily activities. Most of the time, however, physics is overlooked and never acknowledged. It is important to understand different aspects of physics because physics tells us how and why certain events occur. By definition, physics is the search for laws that describe the most fundamental aspects of nature: matter, energy, force, motion, heat, light, and other phenomena. There are many different sectors of physics, but we...

It can be uniform, with constant angular rate of rotation (and constant speed), or non-uniform with a changing rate of rotation.

Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each...

There are three laws of motion that have been stated by Sir Isaac Newton during the sixteenth century that are looked upon even today.

The second of these laws states that when a force acts upon an object it causes it to...

In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of velocity, acceleration, displacement, and time.[1] Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame.
A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change...

Centrifugal force
Centrifugal force (from Latin centrum, meaning "center", and fugere, meaning "to flee") is the apparent outward force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body as the body's path is continually redirected. In Newtonian mechanics, the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame, and...

Physics is how everything in the world works in harmony. Without it, things would be floating around, the earth wouldn’t rotate, and it’d be a huge mess. Newton’s laws of physics are the best way to explain how the physical world works.
Newton’s first law of motion states “an object at rest will remain at rest and an object in motion will continue moving at a consistent velocity unless acted upon by a net force. A real world example of this would be playing golf. The golf ball sits on the...

An air track is an apparatus that simulates the effects of frictionless motion. A known mass is attached to an air-cart on an air-track apparatus. Attached by string, the air-cart is pulled by the known mass when hung over a pulley. A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment, enabling the system of masses to move without an applied force...

NEWTON’S SECOND LAW: ATWOOD MACHINE
Introduction
One may study Newton’s second law using a device known as Atwood’s machine, shown below. It consists of a pulley and two hanging masses. The difference in weight between the two hanging masses determines the net force acting on the system. This net force accelerates both of the hanging masses; the heavier mass is accelerated downward and the lighter mass is accelerated upward. This system is convenient for studying motion under constant...

Roller Coaster
For many people, there is only one reason to go to an amusement park: the roller coaster. Some people call it the "scream machine," with good reason. The history of this ride reflects a constant search for greater and more death-defying thrills.
How does a roller coaster work?
What you may not realize as you're cruising down the track at 60 miles an hour is that the coaster has no engine. The car is pulled to the top of the first hill at the beginning of the ride, but...

1. The drawing shows three containers filled to the same height with the same fluid. In which container, if any, is the pressure at the bottom greatest? (a) Container A, because its bottom has the greatest surface area. (b) All three containers have the same pressure at the bottom. (c) Container A, because it has the greatest volume of fluid. (d) Container B, because it has the least volume of fluid. (e) Container C, because its bottom has the least surface area. 2. Three solid objects are...

Abstract
This experiment measures the study of motion by observing the force of gravity acting solely upon an object, and also measures reaction time. If an object is in free fall, the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion, when dropped. The...

Aim
To investigate the relationship between the constant force applied on a given mass and the acceleration it produces
Apparatus
Trolley
Brick
Elastic bands
Meter ruler
Ticker tape
Ticker timer

Procedure
1. Put the brick on the trolley.
2. Line the trolley up on the runway near to the timer.
3. Link trolley near timer on runway to meter ruler by means of an elastic band loop.
4. Push the meter ruler to move trolley, keep the length on the elastic...

The biomechanical principle :
Principle #1- Stability
The lower the centre of gravity, the larger the base of support, the closer the line of gravity to the centre of the base of support, and the greater the mass, the more STABILITY increases.
There are two types of stability:
1.) Linear
a.) Static- at rest a person stability is proportional to the mass and the frictional forces between the person and any supporting surfaces.
b.) Dynamic- While moving a person's linear...
